I've made this comment earlier in the thread, but I will make it again. I've followed the 1M forums, and in 80F+ weather they are seeing very high oil temps. Guys are hitting 280F after just a few laps. Sorry but the PPK won't cut it. IMHO. Its just 0.5L more of radiator, which obviously won't do a thing, especially with the 1M's additional power, and thus heat. Most of us see the exact same results by turning on the heater. The coolant then flows through the heat exchanger (0.5L), and is blown by a fan. Same exact thing as adding an auxiliary radiator. The PPK also adds a larger fan, and runs the water pump harder. All that still doesn't hold a candle to STETT/ER Oil cooler + diluted coolant and water wetter.
